Atrial fibrillation can be interpreted by noting.

Atrial fibrillation is a rapid, irregularly irregular atrial rhythm. Symptoms include palpitations and sometimes weakness, effort intolerance, dyspnea, and presyncope. Atrial thrombi may form, causing a significant risk of embolic stroke. Diagnosis is by electrocardiography.Alcohol is the most common trigger of atrial fibrillation reported by 35% of patients 9 and is associated with autonomic modulation with reduced heart rate variability, 10,11 sympathetic effects ...Atrial fibrillation requires treatment to convert the rhythm back to a normal sinus rhythm with one atrial contraction for every ventricular contraction. Normal sinus rhythm, in which the rate is 60 to 100 beats/minute, requires no treatment. Text Reference - p. 800. A patient has a heart rate of 150 beats per minute.Abstract. Atrial Fibrillation (AF) is a common heart arrhythmia that often goes undetected, and even if it is detected, managing the condition may be challenging. In this paper, we review how the RR interval and Electrocardiogram (ECG) signals, incorporated into a monitoring system, can be useful to track AF events.Atrial rhythms originate in the atria rather than in the SA node. The P wave is positive, but its shape can be different from a normal sinus rhythm because the electrical impulse follows a different path to the AV (atrioventricular) node. Common atrial arrhythmias include premature atrial contractions, atrial fibrillation, and atrial flutter.

A major limitation of clinical AF studies is that classic interpretation is challenging, focusing on unipolar and bipolar electrogram activation timing and qS-type …
